Sensor Offset Menu
This menu is accessible through normal operation mode. The Mode Selector Jumper (JP1) must be set to the RUN position
(Operation Mode).
1. Press the
and
keys for 5 seconds. The
“Enter Password”
screen appears.
2. Enter the password (
372
) within 1 minute. Use
the

arrow keys to increase or decrease the value and the
,
buttons to toggle between the digits. If
you enter the wrong password, the controller displays “

The controller will return to normal mode if you navigate through the entire menu and do not make any selection, or if you do not
press any key for 5 minutes. The changed values will be saved automatically.
“Intern
Temp Sensor Offset”
Range:
Offset:
Increment:
0ºC to 50ºC
[32ºF to 122ºF]
Max. ± 5ºC
[± 9ºF]
0.1ºC
[0.2ºF]
Compare the displayed temperature reading with a known value from a thermometer or other temperature sensing device. To
offset or calibrate the sensor, use the arrow buttons to set the desired temperature reading. This is useful for controllers installed
in areas where the temperature read is slightly different than the room’s actual temperature. For example, a controller placed
right under the air diffuser.
“Extern Temp
Sensor Offset”
Range:
Offset:
Increment:
-40.0ºC to 100ºC [-40ºF to 212ºF]
Max. ± 5ºC
[± 9ºF]
0.1ºC
[0.2ºF]
This option appears only if you have selected
t10.0
or
t10V
at Step 80, "UI1 Signal Type" or Step 84, "UI2 Signal Type". The
display shows the temperature read by the external temperature sensor. Adjust the offset by comparing it with a known value
(e.g. thermometer). If the sensor is not connected or short circuited, the unit displays the sensor's limit.
"Extern Humidty Sensor Offset"
Offset:
Range:
Increment:
± 5%
10% RH to 90% RH
0.1% RH
This option appears if the controller is set to use an external humidity sensor. The display shows the relative humidity
percentage read by the external humidity sensor. Adjust the offset by comparing it with a known value humidistat. If the sensor
is not connected or short circuited, unit displays the sensor's limits. The humidify
symbol is also displayed.
"VFD Pressur Setpnt"
Default:
Range:
Increment:
500 Pa
100 to pressure maximum range
1 Pa
This option appears only if you have selected
VFdP
at Step 17 "AO2 Ramp", and
P10V
at Step 80, "UI1 Signal Type" or Step
84, "UI2 Signal Type". Select the setpoint value for VFD pressure. The fan
symbol is also displayed.
"VFD Temp Setpnt"
Default:
Range:
Increment:
22.0ºC
[72ºF]
10.0ºC to 40.0ºC [50ºF to 104ºF]
0.5ºC
[1ºF]
This option appears only if you have selected
VFdt
at Step 17 "AO2 Ramp". Select the setpoint value for VFD pressure. The
fan
symbol is also displayed.
